8.2 Adjusting the label position
The position value defines which distance the goods travel after scanning (detection) until the label is
sticked on. With this function it is not necessary to shift the goods scanner to change the label positi-
on on the goods.
As the adjustment of the position value depends on the labelling speed, it has to be monitored conti-
nuously. The following values are monitored:
Position value when entering a fixed speed
Fixed speed with too small position value
At measured labelling speed, the minimum position value
The minimum position value depends on the maximum labelling speed. The labeller needs more time
at high speed to accelerate the label after detection of the goods. The following diagram shows the
position value vs. labelling speed:
Position value [mm]
Labelling speed [m/min]

Attention:
Four encoder steps are required at least when measuring the speed with the in-
cremental encoder to calculate the actual speed. That means, that the minimum
possible position is four times the encoder step length.
If the value of the position adjustment exceeds the distance between the goods,
not each good will be labelled as the goods scanner is not monitored during la-
belling.
Note:
The position value and the predispensing influence both the position of the la-
bel on the goods. If predispensing is increased, the label will also be sticked
more downstream.
